CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 247,198, datedSeptember 20, 1881.

Application filedFebruary 1,1881. (No model.) i

To all whom it may concern:

Be it known that I, IRVING W. KEITHLEY, of Chicago, in the county ofCook and State of Illinois, have invented a certain new and usefulImprovement in Car-Couplings, of which the following is a specification.

The object I have in view is to produce a cheap, simple, and durableautomatic carcoupling, which will be convenient in use, can be readilyuncoupled, can be coupled with allsizes of links, and,when the automaticswinging pin is broken, can be used with an ordinary pin until againprovided with an automatic pin; and my invention therein consists in thepeculiar devices employed by me for this purpose, as fully hereinafterexplained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is a topview of the coupling; :Fig. 2, a vertical section of the same; and Fig.3, a vertical section, showing the drawhead coupled with a short link bymeans of an ordinary pin.

Like letters denote corresponding parts in all three figures.

Ais the draw-head, havinga flaring mouth, a.

B is a swinging pin, which is pivoted at its upper end by means of abolt, 11, between lugs C, rising from the draw-head at the center of itsfront edge. This pin is offset to the rear from its pivot, as shown by0, and its body hangs down vertically into the draw-head, passingthrough a longitudinal slot, D, in the top of the draw-head, and into aslot, E, in the bot-- tom of the draw-head. The upper slot, 1), is madelong enough so that the pin B can be swung entirely out of thedraw-head, while the lower slot, E, need only be equal in length to thewidth ofthe swinging pin. This swinging pin rests against the ends at eof the slots, and the. strain upon the pin is all taken by the draw-headat the points (I 6, so that the pivotbolt 1) will be relieved fromstrain and will not be broken off or become bent.

The lower end, f, of the pin B is formed on acurve struck from thefulcrum b, and the inner lower corner, f of the pin rises above theupper surface of the bottom plate of the drawhead to a point just belowthe center of the end of a linkrestin g on the bottom of the drawhead.This peculiar construction is for the purpose of allowing the swingingpin to be raised when there is the least play between the link and thepin. The pin B is raised by suitable connection with the ring g, so thatit can be operated from the top or side of the car.

The pin B can be thrown upwardly into the position shown in Fig. 3, andwill be prevented from falling forward and interfering with the abuttingdraw-head by means ofa shoulder, h,

on the top of the pin, which rests on the drawliead. This shoulder,however, allows the pin to swing far enough forward so that it willretain itself in its reversed position. When the pin B is swung upwardlyan ordinary straight round pin, F, can be droppedinto the forward endsof the slots 1) E, such slots being enlarged at those points for thispurpose to form round holes G H, the other portions of the slots D Ebeing of less width than the diameter of an ordinary round pin. Theswinging pin B is likewise of less thickness than an ordinary pin. butitis of greater width, being made flat, and preferably of plate-steel.

Cars will be occasionally met with whose draw-heads have links so shortthat they will not couple with the swinging pin, by reason of its width.When suchis the ease the swinging pin is thrown up to the position shownin Fig. 3 and the ordinary pin is used. swinging pin is broken, anordinary pin'can be used entirely until the draw-head is provided with anew swinging pin.

What I claim as my invention is-- 1. In a car-coupling, the combination,with 5 the draw-head A, having slots I) E, enlarged at their forwardends to form round holes G H,

and provided with lugsC forward of such slots,

of the broad flat swinging pin B, pivoted between the lugs C and offsetto the rear at c, 9

and hanging vertically in the slots 1) E, such pin bearing against theforward ends, d 0, 0t said slots, and adapted to swing wholly out of thedraw-head, to make room for an ordinary round pin, substantially asdescribed and shown, for the purpose set forth;

2. In a oar-coupling, the combination, with the draw-head'A, havingslots D E, enlarged at their forward ends to form round holes G H,

ofthe flat swinging pin B, pivoted to lugs C on the draw-head, andhaving shoulder h, substantially as and for the purpose set forth.IRVING W. KEITHLEY.
